OSTI ID:6748949

Total sulfur in natural gas can be determined by hydrogenation over a platinum gauze at 900/sup 0/C and reaction of the hydrogen sulfide so formed with a zinc acetate solution. The zinc sulfide so formed is reacted with N,N-dimethyl-p-phenylenediamine in acid solution to form methylene blue for final determination by absorbance methods. The method is applicable to natural gas containing not more than 1.0 grain of sulfur/100 ft/sup 3/ and not more than 0.5 percent of C/sub 5/ and heavier hydrocarbons. Duplication of results by this method is +-10 percent for 0.2 to 1.0 grain S/100 ft/sup 3/, +-0.2 percent for 0.05 to 0.2, and 0.01 percent below 0.05.
